luufmzz m which isindividual to the second set of jacks. Thus, it will be seen that even though the registers may be each of nine or more denominations, still only'three or four denominations of each thereof will be brought into use by the dogs so that narrow columns may be typed in juxtaposition upon the work-sheet, and the numbers typed in the first column will be added only inthe first register, while those typed in the second column will be added only in the second.

re ister.

.henever desired, either register may be used to its full capacity, by substitutinga dog having a displacement cam which is equal in extent to the entire set of jacks, say'nine letter-spaces of the'typewriter carriage; or both dogs may have full-capacity cams. Any dog is not only adjustable along the carriage, but also movablefar to the left or right out of range of any totalizer, or removable from the machine when not required, as disclosed in Hart Patent 1,17 6,36 1. A complement of dogs, some of which have short, others of which have medium, and still others of which have maximum length elevating or cooking cams, will, therefore, impart flexibility or adaptability to the machine, enabling each register to be used for i a very narrow column, or for medium width,

or for a very wide column, regardless of the width of the column for which the other register is used, and permitting all columns to be typed as closely together as desired. It is further noted that this may be accom plished by a very simple and inex ensive change in existing machines of the nderwood-Hanson type, illustrated in the patents herein mentioned. It will be understood that three, four or more registers may-be employed, with corresponding sets of jacks, and that the jacks for each register may differ from those for any of the other registers, as illustrated for example in the patents to Hart 1,190,171, 1,190,238 and 1,231,523, in which the jacks for the'second register are longer than those for the first, and the jacks for the third register are longer than those for the second; the respective dogs being out of line with one another or in echelon arrangement, so that the dog for the first register will not affect adding may be simultaneously performed by the use of a third register, having a succession of the described dogs for operating the denomination'jacks thereof, there being as many cross-adding dogs as there are columns to be cross-added; and that these crossadding dogs ma each be provided with an elevating cam 0 suitable length to meet the requirements of the case, short-cam dogs being used for numbers of few denominations, and being locatable close to one another, to agree with the spacing of the columns upon the. work-sheet. Hence, although all'of the registers may be of large capacity, still narrow columns may be typed closely together upon the work-sheet, and the numbers therein may be added vertically, while cross-addition of such numbers may be made at the same time in the cross-adder. When desired, the machine may be used for writing and adding only wide columns, or both wide and narrow columns, with the columns spaced as closely together as desired on the sheet, while the results of the cross-additions will show in the cross-adding or grand-total register.

Another feature of the invention relates to increasing the adaptability of the machine in still another way, which is, by making it practicable to compute separately in a singlelar e totalizer two or more narrow columns of numbers, while permitting such columns, if. desired, to be typed closely side by side upon the work-sheet. To this end, a se arate denomination-selecting dog is provided for each of the narrow columns, and eachof these dogs is in line with all of the jacks in its own register,although preferably outof line with jacks upon other registers; and

in carrying out this feature of the invention, one dog is used for say the lowest three denominations in the register, a second dog portion of the register, elevating cam upon the second dog is staggered or placed stationarycams, and that'they are arranged to'correspond with the elevating cams upon the dogs; one stationary cam being placed.

at the lowest portion of the set of jacks, another stationary cam out of line with the first'and arranged at the middle portion of the set of jacks; and a third stationary cam outof line with the two others and arranged at the upper portion'of the set of jacks. It Will thus beseen that these three dogs may be assembled closely together to permit the close typing of the columns upon the worksheet, and thusthat a single register may be used foradding separate columns written side by side. The number of such columns may,of -course,'be.more or less than three, and the numberfof denominations in each columnmay be'more or less thanthree, At any time by substituting a dog having a long elevating. cam, the' same totalizer may be used for adding numbers of many more denominations typed in a single wide column upon the w0rk-sheet-.- a

Itwill be seen that as to certain relevant featurea'this invention presents advantages over the invention disclosed in the Griffith Patent 1,263,881,:since the present device has greateradaptability and is easily made and applied to existing machines, and enables 'the' jacks to be of uniform length throughout for each register, so as to he capable. of-use with all lengths of elevating cams; so that theregister need-not remain. 'permanently'spllt'; while the advantage is preserved'of using difierent lengths of jacks for different registers, e'ach whereof mayor may not be splittable by means of the described disalined or'ofi'set elevating cams.

It will be further understood that the aforesaid cross-adding mechanism can be used to cross-add the narrow columns,which are added vertically in a single totalizer in the manner .just described.

It will be further understood that while onetotalizer or register may be used for adding separately two or more colu1nns',ianother register may he need for adding still another column, or for a'dding-twoior more narrow columns infthe fmanner just described, so that, for example, sir; narrow; colu'mns may be -wr-itten closelytsiderbyggside upon the worksheet and added vertically by the use 5 ot only two ""totaliaers, "thus greatly "increasing pacity of the machine :three* totalizers afi the "adaptability;:and v.ca-

The extreme right-handregister may be' used for the cross-adder, and the rack which carries all of the dogs may be extended to the right as far as necessary, in order 'to give: room tor-the location of as many'dogs' as are required for operating the cross-adder for the required number ofcolumns. U The invention may be alsoemployed in some cases to pertormhOiihYertical and cross-addition of narrow columns in a single totalizcr,which preferably may have twelve or more denominations:- Tliej first dogcould operate say the three lOWeSt-jaCkS f r add.- ing the numbers in onecolumn vertically; the second dog could be-used f or operating three or more=jacks in the middle portion of the set, for adding verticallyithe num:

jing operated inthis manner, mini-total izer can be operated for-adding vertically and cross-adding the; numberewrittenin other columns on the same vorlnsheeh and so on. l I 11,5, When it is desired simply Qto cross-add without adding any column v.ertically, very many narrow columns may be typed closelyj side by side upon the worksheet, and the denomination-selecting dogs, one for: eacli column, may be set: sufiiciently plosdt gether, since each dog-mayhave ash'ort, l

Fig. 7 a is a detail view of' one of the camcarrying bails.

Fig. 8 is a part sectional plan of devices As described in said patents, the t pewriting mechanism comprises numeral eys 10; and alphabet keys 11 which are connected by levers 12 to type-bars 13 to throw the latter against the platen 14, which is mounted upon-acarriage 15.- For the purpose of letter-feeding, the carriage is provided with a rack-. 16 whitzhfisfonnected by a pinion 17 to an esea-pement wheel 18, which is controlleddogs 1-9 the latter moved by a universal bar 20, which is operated by the type-bars. The carriage feeds step by step under the influence of a driving spring (not shown) atthe operation of the type keys.

As also set forth in said' patents, the- Underwood-Hanson machine comprises computing mechanism connected with the-numeral keys 10, said keys hav ng stems 21 which operate arms 22 upon rock shafts 23,

the latter connected to transverse horizontal bars 24 which are movable downwardly for 1 the purpose of depressing or setting up index pins 25 when the keys are depressed. The index pins are arranged in rows, nine in each row, there being as many rows as there are denominations in the register. Each row of index pins is'mounted u ion a movablebar 26. These bars are placed side by side and extend forwardly and rearwardly. The in- .dex pins are normally out of range of any of said transverse bars 24 but any row may -be moved into range of all of said bars 24.

These movements or displacements ofthe index-pin bars 26 are effected automatically by the typewriter carriage. For this purpose, there is mounted upon the carr age a denomination-selecting dog 27, which, during the movement of the carriage, will lift, one after another, all the jacks 28 in a set, sald jacks bein mounted at the rear of the machine, an being in the form of levers. whose rear arms depress rods 29, which are connected by levers 30 and a transposition device 31 to bell cranks 32 arranged in rear of the bars 26 which carry the index pins 25; the operation being that when the selecting dog 27 on the carnage strikes any denomination jack 28, the latter is lifted and its rear end depressed, thus carrying down the link 29 and moving the corresponding. member of the transportation device 3 1, to rock the associated bell crank 32, whose upright arm presses forwardly the bar 26 which carries the index pins 25 of the same denomination as the jack 28 which is so actuated. Hence, all of the index pins on said bar 26 are brought into range ,of the key-operated cross-bars 24, to enable the latter to set any pin in this row. After all the index pins have thus been set up for any number, the. bars 26 are all driven forwardly by means of the set-up pins, and by 'means of gears 33 at their front ends revolve dials 34, of which there are usually nine or more in the register. This movement of the rack bars is effected by a'general operator 35, which may be operated either manually or by power, and is in some cases operated automatically, as set forth in said patents, and others.

The denomination-selecting dog 27 is in ineffective'position except when the typewriter carriag'e 15 'is in a computing zone, that is, in such a position that the numbers typed upon the work-sheet may be computed by-the register. To enable it to move into and out of effective position, the dog 27 is carried upon a mount 36 which can swing up and down upon a horizontal rod 37, which is fixed to the typewriter carriage. Moreover, the dog with its mount may be adjusted along said rod, and may be accurately located by means of one or more teeth 38 depending therefrom in position to engage the teeth of a horizontal rack 39 which also extends along the carriage. Up-and-down movement of a dog into and out of effective position is disclosed in Gumprecht Patent 1,268,565, and ThorntonPatent 1,238,055, etc., but in said patents the movement of the dog into effective position is controlled by a stationary cam which extends the entire length of the set of jacks, to raise the dog during its entire movement past the set of jacks. Hence, if two dogs in said patents were adjusted closely together, both would become effective upon jacks in the same register at the same time, resulting in erroneous calculations; whereas the present invention provides means whereby two dogs may be traversing the same set of jacks while only one otthose the dog should operate; whereas in the present case, each dog has its own independent determining means. The stationary sum or shoulder all has no substantial length, and hence can cooperate with elevating of different lengths upon diflierent dogs. lhe dog cam 40 is preferably in the term of a roller extending horizontally in the direction of the travel of the carriage, and pivoted in ears 42 formed in a bracket 43 which depends from the dog mount 36; While the stationary cam ll is preferably in the form of a wheel which is mounted upon a forwardlyextending horizontal pivot carried by a stationary bar or support eetfthsrt is, a bar which does not travel with the carriage. The dog, its elevating earn and the stationary cam may be so placed that the elevating cam will ride oil from; the stationary cam just as the dog passes or relinquishes the jack of lowest denoniins.- tion; the lengthoithe elevating cam determining how many jacks shall be operated by said dog'during the "traverse oi the jackset thereby. It will be understood that the dog maintains its'depressed ineffective position while traversing the jack-set, until the elevating cam encounters the stationary cam and is raised thereby to effective position, as at Fig. 2, whereupon it will maintain such position while it traverses the remaining jacks in the set.

An assortment of these denominationselecting dogs maybe provided for the machine, as seen in the drawings, some having short cams, some having cams or medium length,and some having cams of a length equal to the width of the entire set of de- I nomination jacks. ,Hence, the operator is enabled, f required, to'perform a variety of work, so as to use each register sometimes {for close narrow-column work, and some timesfor'wide-column work, etc. v The dogs whichfare out of use may he slipped to one end of the'supporting rod 3?, where they wil not be in position to engage any the jacks; ,or, lromtim'e to time, one or more dogs may beremoved"entirely fro 'n the lfiitchine and others substituted, provision be- .ing illustrated in said patents ler' r a tinlg removal of dogs.

Fig. 2, there are illustrated complete sets at jacks belonging to two registers, and the selecting dog27- for one register B is as having passed idly the jacks of upper denominations, and as having been caninied up into position to lift the jack of hundreds denomination; the elevating cam 40 of said dog having just been engaged and elevated by means of the stationary cam ll, as seen. During the writing of the number upon the work-sheet, said dog will proceed to lift the tens jack, and then the units jack. The typewriter carriage will then be advanced idly one space, by means of the usual spacing key at the front of the keyboard. .i uring a portion of the described travel of the first dog, a second dog seenat said figure traversed some of the jacks belonging to the second register A, but without engaging any of said acks, since its elevating cam 40 had not yet reached the stationary cam il'belonging to said set of jacks. in other words, no jack will be raised by either dog during the first portion of its traverse, and no jack will be raised by the second dog while the first dog is raising the last three jacks in the first set. Then the second dog, whose cam 40 now comes into engagement with the stasaid second set. Hence, the numbers put in the second column, while the second dog is lifting the last three jacks in its set, may be typed closely to the numbers that were typed. in the first column; these columns being separated by no more than a single letterspace, if desired. Thus there is effected economy of space upon the worksheet, where it has been the general practice heretofore to separate widely the narrov columns upon the work-sheet, so as to allow each dog to traverse idly all of the unused higher-denomination jacks in the register.

At Fig. 8, the jacks 28 for one register are represented at A, those for another at B, and those for another at C. The jacks B are longer than those at A, and the jacks at C are longer than those at B. The dogs 27 are correspondingly located upon their mounts 36, so that each dog is capable of operating only the jacks of its associated set, and will pass idly by the jacks of the other sets. A similar variation in the lengths of jacks and the locations of dogs described in said Hart Patents 1,190,171, 1,190,233, and 1,231,523. The jacks in the three sets are also illustrated in elevation at Fig. 3, which also shows the locations of their respective selecting dogs. Since'the stationary cams 41 for the'jacksets" and C are all in line, it happens that the dogs are elevated idly by these cams, except when iiny dog is traversing its fownset' of jacks. It will be understood that where in any figure of the drawings two or three registers or gack-sets are indithat are set forth elsewhere in this description.

' column-registers B and C. The ja jacks at A and B.

At Fig. 5, A represents diagrammatically;

a cross-totalizer or register (or-set of jacks for numbers that are added vertically i1;

0 thousands denomination for {the colilmnregisterv B is shown as raised by the dog D, Whose elevating cam 40 has just come into engagement with the'stationary cam 41. This cam 40 is similar to those seen at Fig. 4, but instead of being in roll form, it is in the form of a plate or downward extension of the bracket 43. At the same time, the first dog for operating the register A is shown at E as elevated by cams 40, 41, and holding up the thousands jack in set A. As the number is typed, the aforesaid dogs D, IE, will elevate in turn the hundreds, tens and units jacks on the registers A'and B. Thereupon, dog F will, by means of its cam 40, be forced to elevate the thousands or hundreds jack for the register C, and, at the same time, thesecond dog G for the register A will be forced to elevate the corresponding jack, so that the numbers added vertically in registers and C are cross-added in register A- It will be understood that the narrow columns corresponding with B and C may be typed closely together upon the work-sheet, for reasons already given, notwithstanding the fact that while do s are traversing jacks in both A. and C other dogs are elevating At the right-hand part of Fig. 7, is illus; trated an arrangementwhereby registers may be used for computing in one register numbers in three narrow columns which are typed closely together upon the worksheet. The first dog at H is seen cammed up to hold up the jack 28 of huri'dreds denomination. While the operator proceeds to type numbers in the corresponding col would be the millions jack, but in the pres-' ent instance, it serves as a hundreds'jack, so that as the number is typed in the second column, this dog I proceeds to elevate the succeeding two jacks, which are now used as the tens and units jacks; whereupon the dog I passes by its stationary cam 45 and falls into inefiective position, and thereafter cams 41, 45,. 46

traverses idly the remaining jacks in the set. While said second do I is thus traversi "said remaining jacks, t e third dog J reaches and is lifted by its stationary cam 46' to ele .vate the extreme left-hand jack in the set C, which is likewise used for hundreds denomiinto three registers by the use of the three do H, I, J, and the three pairs of cams. It should be observed that the stationary Fig. 7) are not in line,

so that the dog can be elevated only by its stationarycam 41, the dog I only by-its' stationary cam 45, and the dog'J only by its stationary cam 46, so that this staggered, offset or echelon arrangement of the cams permits the splitting of the register into sev-,

eral parts. It will be understood, of course, that the elevated cams 40 upon the dogs H, I, J are also in echelon, each elevating cam being in line only with its associated stationary cam. Moreover, these three dogs are out of line with the jacks in the other sets A and B (if the sameare present on the machine). Hence, the selection of different portions of a split register is effected by having the cams in staggered or echelon relation, while the selection of registers is effected by having the jacks of each set of different length from those in the other sets. At Fig. 6 is illustrated diagrammatically a method of cross-adding in re ister A the numbers that are vertically adde in three columns in totalizer C, split as just explained. In the cross-register at A only the three lowest jacks are brought into use at this time. These arebrought into play repeatedly b means of the three dogs shown at K, L, NI:

these dogs being elevated one after another by the single stationary cam 45. The three dogs H, I, J, for the register at C, Fig. 6,

operate their respective jacks in the manner just above explained, so that the three narrow columnsmay be typed closely together upon the sheet and added vertically in the single register C, and cross-added in the register A, which, if desired, may be used as a .grand-totalizer. It will be understood that,

if desired, the totalizer A may be provided with staggered stationary cams 41, 45,46, as seen at C,'but that, when the elevating cams 40 of dogs K, L, and M are in alinement with cam 45 as shown in Fig. 6, the cams 45 and 46 will be idle.

Reference is again made to Fig. 7, to illustrate the vertical addition of numbers in six narrow columns by the use of only two registers, as B and C. The operation of the register Cv at this figure has already been explained; and it will be seen further that immediately after the escape of, the third dog J past the third jack from the left at C, the first of the three dogs marked N, O, P will engage the third jack from the left in the set B, both beiiilg elevated by the stationary cam 41 (as at Then the operation will proceed for totalizer B in the manner above described in connection with the totalizer C-at said Fig. 7. The single register'C is thus used for the addition of three closely placed separate narrow columns, while the register B is used for the addition of three more separate narrow columns typed closely to one another and to the first three columns. This is permitted because the typewritter carriage has sufficient travel to enable the use of many adding zones; the jacks of C and dogs H, 1,.J being, of course, idle when the jacks at B and dogs N, O, P are active. It will be understood at Fig. 7 that the dog-carrying rod 37 and the rack 39 may be extended to the left as far as necessary in order to enable the dogs N, O, P to be properly adjusted with respect to the set of jacks of B. While there are illustrated at Fig. 7 only two registers, it will be understood that certain features of the invention have advantages not only in connection with two-register machines, but also in connection with one register machines, as well as in connection with machines having three or more registers.

At Fig. 1 is illustrated diagrammatically a single register Q, having say thirteen jacks and dials. This register is used not only for adding in two narrow columns, typed closely together on the page, but also for cross-adding or securing the grand total of the numbers written in said columns. The first dog R is seen as thrust up by its stationary .cam 41 to elevate the jack of thousands denomination, while the second dog S is thrust uplby its stationary cam 46 to elevat the extreme left-hand jack in the register, which is now also used for the thousands denomination. As the number is typed, these dogs progress toward the right at Fig. 1, and each operates three more jacks for hundreds, tens and units denominations. Then the dogs slip off from the stationary cams 46 and 41, so that the numher is vertically added at the right-hand portion of the register-and cross-added at the left-hand portion. Then the same dog S, which has two elevating cams 40, in line respectively withcam's 45, 46, Fig. 2", is still held elevated by the stationary cam 45, after it passes the; stationary cam 46, and proceeds to f elevate successively the sixth, seventh, eighth and ninth jacks from the left of Fig. 1, and .a thirddog T now engages the four jacks at the extreme left of the register, to cross-add the number which is being added vertically in the middle portion of the register, This third'dog T is elevated by stationary cam 46. If desired, an additional dog U, seen at the extreme left of Fig. 1, may be used subsequently for operating the four jacks at the extreme left of the register, for subtracting the crcss total.

When it is desired merely to cross-add, the arrangement seen at A at the left-hand portion of Fig. 6 can be used, without the totalizer (l, or its three dogs H, I, J. The dogs K, L, M, which operate A, may be placed as closely together as desired, and many more dogs can be placed at their left, each of which will be raised by the station ary cam 41 in turn, so as to operate the three jacks in the set A. Thus, very many narrow columns may be written closely upon the worksheet, and cross-addition thereof "performed. If any of the columns is wide, then there may be used for such column a dog having a longer cam, such as seen at D, Fig. 5, or a still longer one, as seen at Fig. 4. Each of the totalizers A, B and C may be permanently provided with all three of the staggered stationary cams 41, 45, 46, ready to cooperate with appropriate dogs with which the machine may be equipped from time to time. Of course, each of the three cams 41, 45, 46 will elevate the dogs which belong not only to its own register, but also those which are intended to operate the other registers, but such elevation will be idle, since the dogs are not in position to engage the jacks at such times.

At Figs. 4 and 8, the reglster C is split added vertically in the other portion are also cross-added, The four right-hand jacks at C are operable by the first dog V, which is elevated by the stationary cam' 41. The four left-hand jacks at C are opegable by the dog W, which is elevated by th stationary cam 45. The amount added by meansof these four left-hand jacks may be crossadded'in connection with amounts which are added in the register at B; the cross-adding register being'indicated at A. All of the jacks at B are liftable by its dog X, and all of the jacks at A may be elevated by each of dogs Y, Z. The extreme left-hand dog at Fig. 4 may be used for substracting the total from the cross-adder or grand-totalizer A. The numbers added in the right-hand portion of register C are hot vcross-added. The foregoing gives only a few illustrations of numerous uses to which the invention is adaptable. I

Since it is not desired .to perform computation when the case-shifting mechanism of the typewriter is shifted for writing capital letters, the stationary cams 41, 45,. 46 for each register are mounted to be tion by a returning spring 54.- Thisroek shaft is operable by means of a pendent arm which is engaged by an arm 56 extendingrearwardly from a roek-shaft 57 of the case-shifting mechanism 58, which may be the same as set forth in said Gumprecht Patent No. 1,268,565. Said rock-shaft for silencing the dogs may likewise be operated by means of a bell-crank whose horizontal arm 59 engages a shoulder 60 provided upon the shaft 51; the depending arm 61 of said bell-crank being connected to a ro d 62 extending forwardly and. having a noIr-add key 63 at its forward end, as set forth in said' Gumprecht Patent No. 1,268,565; and it will be further understood thatsaid. rockshaft 51' may be operated by the tabulating mechanism, as also set forth in said patent. There is provided one bail 47, 48 for each of the registers, and all of the bails are fixed upon their rock-shaft 49, so that all of the adding mechanisms are silenced at the caseshifting operation, or at the'operation of the non-add key, or at the back-spacing operation, or at the tabulating operation, etc.

The cams maybe detachably secured to the dogs by screws 64 as shown, so as to be interchangeable so that by having a number of bodies and an assortment of cams, any

desired system of dogs may be provided, thus conducing to economy. It will be understood that four or more registers may be employed. Where in. the claims the word jacks isgused, it is intended to include not only the levers shown, but also any kind of device whereb the selection of denominations can be e ected; and it is not necessary in all cases that the dog or equivalent device engage directly with the jack or equivalent device.

Variations may be resorted to within the seope'o'f the invention, and portions of the improvements may be used without others.
